Product Name:Helium-3
English Name:Helium-3
CAS No.:14762-55-1
Aliases:Helium-3, 3He, He-3
Molecular Formula:3He
Physical Properties:At room temperature and pressure, it is a colorless, odorless, non-toxic inert gas with extremely low chemical reactivity. Boiling point is about 3.19 K (-269.96 °C), and critical temperature is about 3.35 K, making it one of the lowest-boiling liquids known. Gas density is approximately 0.00045 g/cm³ (at STP), slightly soluble in water, and very slightly soluble in organic solvents.
Uses:Helium-3 is an ideal fuel for nuclear fusion reactors; its fusion reaction with deuterium delivers high energy output with almost no radioactive waste. In low-temperature physics, helium-3 is used in dilution refrigerators to reach ultralow temperatures near absolute zero. It is also employed in neutron detectors, polarized gas for MRI, and cutting-edge research fields such as quantum computing.
Technical Specifications:
Isotopic abundance: 99.9%
Molecular weight: 3.01603
Storage condition: high-pressure cylinder or cryogenic Dewar vessel
Colorless and odorless inert gas at room temperature, chemically stable
Used as nuclear fusion fuel and cryogenic scientific research medium
